Macclesfield Canal Marple
Macclesfield Canal Marple
The Macclesfield Canal runs between Marple and Hall Green, near Kidsgrove, UK. It passes through Bollington, Macclesfield and Congleton. It is about 26 miles long and has 13 locks. It links the Peak Forest Canal with the Trent and Mersey Canal and forms part of the "Cheshire Ring". Opened in 1831, the Macclesfield Canal was one of the last canals to be built in Britain. Adjacent the stone building is a Stop Lock. Although the Macclesfield and Peak Forest canals canals were built to the same level, the lock was provided for when water shortages might have resulted in a temporary difference.The lock has long been de-gated, having become unnecessary once the Macclesfield and Peak Forest canals came into common ownership. The site of the lock remains as a narrowing just in front of the junction bridge, overhung by a loading canopy.
Warwick Stop Lock and Banana Warehouse
Warwick Stop Lock and Banana Warehouse
The stop lock, or bar, is a physical barrier to prevent water loss (or theft) from one private canal to another, in this case the Digbeth branch of the Birmingham Canal Navigations and the Warwick and Birmingham Canal (now the Grand Union). Here the stop lock consists of two opposing lock gates at each end of a lock so that a boat could be transferred from one canal to the other with a minuscule amount of water loss, and no water flow, no matter which canal happened to be the higher at any particular time. Today the gates are chained open as both canals are under common control. The adjacent Banana Warehouse with its overhanging canopy is so named as it was once owned by Geest. Both are grade II listed
